The aim of the study was to gain a better understanding of radio signal variability in different clutter types in order to aid the modelling of potential coexistence issues with DTT using the UK DTT planning model. Using our survey vehicle extensive measurements at different antenna heights and locations were carried out to gain detailed understanding[…]
Plum undertook a critical review of a report “The value of Digital Terrestrial Television in an era of increasing demand for spectrum” published in January 2014 by Digital UK. Plum’s critique focussed on the methodology used to estimate the economic benefit of DTT and the average and marginal value of spectrum.
Plum and Farncombe developed for the GSMA a summary of the benefits of digital broadcasting that flow to players on the broadcast value chain. The benefits for the broadcasting industry of the transition to DTT include: An increase in the capacity of broadcast transmission networks by improving spectrum efficiency (i.e. more data can be transmitted per[…]
Plum provided the GSMA with independent estimates of the economic value of eight major applications of spectrum. These applications included mobile services, wireless LANs, terrestrial broadcasting, and satellite broadcasting. The consumer surplus generated by these applications was estimated across the EU 27 member states in 2013 and 2023. In each case the methodology and assumptions[…]
This report considered Ofcom’s proposals for the potential application of AIP to spectrum utilised for national terrestrial TV broadcasting. In its consultation on spectrum pricing for broadcasting, Ofcom stated that, where there are constraints on spectrum release, it does not expect “…the application of AIP to meet its core objective of securing the optimal use[…]
Plum and Aegis advised the Media Development Authority of Singapore on the development of a Code of Practice for TV broadcast standards. The study included a review of international standards and regulations for broadcast TV services across different distribution mechanisms including terrestrial broadcasting, cable, IPTV and over-the-top (OTT). A consultation with stakeholders was also conducted.[…]
Plum and Farncombe prepared a practical guide to digital switchover to supplement the information already published by the ITU and others. The guide focuses on a set of practical measures that anyone undertaking switch over / switch off must address, drawing on best practice from around the world.
It was being proposed that DAB receivers should carry some form of certification mark, to indicate an acceptable level of performance. To allow such a scheme, it was necessary to develop a robust and repeatable method for receiver sensitivity testing. This study compared the sensitivity measurements obtained using two different test methods – one using[…]
The Digital TV Group (DTG) were concerned that they have little visibility of the issues surrounding spectrum use and regulation at UHF and elsewhere. A bespoke brainstorming / workshop session was developed and delivered to meet their requirements.
Plum, with TNS, assessed the economic potential for cross-border pay-to-view and/or listen audiovisual media services in the European Union. The study involved a review of the supply of audiovisual services over terrestrial, cable, satellite, IPTV and over-the-top platforms both nationally and across the EU, and consumer surveys on interest and willingness to pay for such[…]
